What is the functions of placenta as far food concerned?

1. Nutrient exchange: The placenta allows the exchange of nutrients between the mother and the developing fetus. The mother's blood, which is rich in oxygen and nutrients, flows through the placenta and into the fetal bloodstream. The fetal blood then returns to the placenta, where waste products such as carbon dioxide are removed and transported back to the mother's bloodstream.

2. Storage: The placenta stores nutrients and oxygen so that they can be available to the fetus when needed. This is important because the fetus is not able to regulate its own body temperature or blood sugar levels.

3. Transport: The placenta transports nutrients from the mother's diet to the fetus. These nutrients include proteins, carbohydrates, fats, vitamins, and minerals. The placenta also transports oxygen from the mother's lungs to the fetus and removes waste products from the fetal bloodstream.

4. Metabolism: The placenta plays an important role in the metabolism of nutrients. The placenta converts carbohydrates into glucose, which is the fetus's main source of energy. The placenta also converts proteins into amino acids, which are used to build new tissues in the fetus.

5. Regulation: The placenta regulates the flow of nutrients and oxygen to the fetus. This is important to ensure that the fetus receives the nutrients it needs to grow and develop properly. The placenta also regulates the levels of hormones in the mother's body, which helps to maintain the pregnancy.
